Abstract

Procédé et dispositif pour la reproduction de l'image d'une couche d'objet tridimensionnel, les parties d'images obtenues de la sorte suivant des directions différentes étant emmagasinées soit séparément, soit comme image de superposition commune. Pour reproduire l'image d'une couche, les images obtenues suivant les directions différentes sont décalées les unes par rapport aux autres et ensuite superposées. Les points d'image qui, dans les images obtenues suivant différentes directions, appartiennent les uns aux autres, subissent une discrimination par une opération logique, par exemple une addition ou une multiplication, pour définir si oui ou non lesdits points appartiennent à la couche que l'on désire examiner. Exclusivement les points d'image choisis de la sorte font partie de l'image finalement obtenue. Application à l'appareillage tomographique opérant par ordinateur.
